Conductive fluid leak detection system &amp; automatic shut off valve

ABSTRACT

A flood control device and system which controls conductive fluid(s) in a conductive fluid supply line and or path, using the conductivity of said fluid(s). The conductive fluid system comprises; a conductive fluid supply line, in-line conductive fluid shut-off valve, in-line conductive fluid detector, conductive fluid sensor(s) (attached in or to conductive fluid dependent appliances), a D.C. powered central processing unit, and control panel. The conductive fluid flows through said conductive fluid line, said in-line conductive fluid shut-off valve, intern reaching said in-line conductive fluid detector which detects the flow of conductive fluid, thereby sending data to said central processing unit. When said central processing unit receives said data, said central processing unit delays for a predetermined amount of time (example 3 seconds) waiting to receive data from one or more of said conductive fluid sensor(s). If said central processing unit doesn&#39;t receive said data from said conductive fluid sensor(s) within said predetermined, said central processing unit will automatically send data to said in-line conductive fluid shut-off valve, to close, therefore terminating the forward flow of conductive fluid(s). System also includes audible signal(s) to signal an alarm condition, timing mode(s) for water conservation and monitoring in-line conductive fluid shut-off valve movements, a phone notifier for notifying user of said termination of conduct fluid due to a conductive fluid leak detection, and for (user-set) excessive water usage, means for communicating with said central processing unit by way of telephonic communication (to close or re-open said in-line conductive fluid shut-off valve), a battery back up system, and means of operating by way of manual means.

BACKGROUND OF INVENTION

[0001] 1. Field of Invention;

[0002] “The Invention is generally directed to fluid flow control systems and, more particularly, to a system for preventing unwanted conductive fluid flow, particularly water flow, when ever a break in a conductive fluid line occurs.

[0003] 2. Description of Related and Prior Art;

[0004] The damage cause by water leaking from a broken water line in a house or building can be extensive and typically exceeds several thousand dollars per household. Water destroys carpet, drywall, hardwood floors, linoleum floors, etc. and can even cause an floors foundation to warp. Water leaking into a home or building also can cause mold to grow in and around your walls and floors. Some of these molds have been known to cause serious medical problems and on rare occasions even death, for those who are exposed to it for an extended period of time. While the present inventor has no specific evidence as to how much water damage occurs in the U.S. alone each year, it is expected to run into the hundreds of millions of dollars annually. Accordingly, a need exist for a system that will minimize the water damage which results when a break in a home or buildings water line occurs. The seriousness of this problem is evidenced by the large volume of patents filed in the US alone. By way of example U.S. Pat. Nos. 6,186,162, 5,967,171, 6,369,714, 6,025,788 discloses an automatic shut-off device that requires sensors that are placed under or around water dependent appliances, in order to detect water that has leaked from a pressurized water line and has reached the floor. U.S. Pat. No. 4,845,472 provides an apparatus which responds to the sensing of water leakage from a water line of a “hot water” system. U.S. Pat. No. 5,190,069 utilized wire embedded in insulation tape carrying leak detecting liquid sensing elements. U.S. Pat. No. 5,229,750 uses a float and solenoid system to control a shut off in the event of a water leak. U.S. Pat. No. 5,632,302 discloses an over flow detection device for use with a water heater.

[0005] U.S. Pat. No. 6,216,727 discloses an apparatus that starts a preset timer when flow is sensed through the flow sensor. When the flow of liquid has flowed longer that the preset time of the circuit, then the valve will automatically shut off the supply.

[0006] U.S. Pat. No. 4,180,088 to Mallet addresses this problem with a water leak detection system which uses a water flow sensing device to shut off a valve on the incoming water line when water flow in the line is detected. The system cannot be used during periods of normal water usage since the water flow which results, for example, when a simple faucet is turned on would activate the system and thereby shut off the supply of water. Accordingly, this system is only realistically useable when the home owner intends to be away from home for an extended period of time or does not expect to use the system, for example at night. However, use of the system at night is not realistic either since most homeowners use bathroom facilities at night. An investigation of this prior art shows that most of the patents, such as U.S. Pat. No. 4,845,472, U.S. Pat. No. 5,428,347, and U.S. Pat. No. 5,655,561 generate audible alarms to signal a detected leak. Of these U.S. Pat. No. 4,845,472, U.S. Pat. No. 5,428,347, and U.S. Pat. No. 5,655,561 additionally disclose the use of solenoid-actuated valves in the water supply line. U.S. Pat. No. 5,229,750 and U.S. Pat. No. 5,632,302 also disclose the use of solenoid-actuated valves to cut off a water supply. U.S. Pat. No. 5,029,605 point out that deposits that accumulate in pipes and valves over a period of time may impede the actuation of solenoid-type valves. Also avoiding the use of solenoid actuated valves is U.S. Pat. No. 5,240,022 which incorporates a ball valve in the water supply line. To hold the ball valve in an open position it is coupled to a rotor and a spring is attached to the rotor exerting a counterclockwise torque on the rotor. The rotor is then locked in a valve-open position by a latching arm. The end of the latching arm contacts a trip arm that receives it's retaining torque from a wire spring. A trip wire actuates the trip arm. This trip wire is a metallic memory alloy wire which contracts when heated. Heating is effected by a circuit actuated by the water detector. As a consequence the latch arm is released and the rotor rotates to a valve-closed position.

[0007] U.S. Pat. No. 5,334,973 discloses a ball valve. This valve controls flow into a hot water tank by using a mechanical drive in conjunction with a multiplayer moisture sensor which incases the water tank liner.

[0008] U.S. Pat. No. 5,161,563 and its counter part U.S. Pat. No. 5,441,070 which also includes an solenoid-actuated valve, incorporates flap type flow sensors located in the water line in order to sense the flow of water. The main water valve, an solenoid-actuated valve, is a normally closed valve, requires power to open the valve, and only opens when one of the flow/pressure/sensors located at or near an water dependent appliance is activated. When one of the flow/pressure sensors is activated, it sends electrical current to the circuitry to open and “hold open” the “normally closed” solenoid-actuated water valve, thus sending water through the system. This system also has a timed out period and learning periods for each sensor, pressure switches, and temperature sensors as well. This system requires that the water pipes retain its normal water pressure during the time in which the water in not in use, in order for the flow/pressure sensors to trigger when a water dependent appliance is requesting water. If the pressure drops in the system for any reason while the water in not in use, (ie dripping faucet, shower head, running toilet due to a bad flap, etc . . . ) then when water is requested from a water dependent appliance, the pressure in the water pipes will not be enough to trigger the flow sensor in order to ultimately turn the main water valve “on” and receive water to the water dependent appliance that was requesting it. It states that it “the system also thus periodically replenishes itself to compensate for a small tolerable leaks”. This seems to contradict other statements in this patent that states, “this system can sense even small leaks”. If water is requested and not received, due to the confusion of what is a “small tolerable leak”, there would be no clear sign as to why the water system was not allowing the water valve to open, intern letting water to run through the water pipes to its requested location. A few examples of this are that, the pressure could have dropped due to a faucet drip, shower drip, or etc . . . Power could have been interrupted to the main water valve, thus making it impossible for it to open, or there could actually be a small or large water leak in the pipe. This system also requires the main water valve to open (and be held open for the duration of the water consumption) every time water is requested, and every time it needed to “replenish itself”. This would open and close the main water valve at least dozens of times a day, every day 365 days a year, which would not only consume excessive power, but would also deteriorate the life expectancy of the main water valve, and circuitry tremendously.

[0009] In U.S. Pat. Nos. 5,771,920 & 5,503,175, also discloses predetermined time and or “timed out” periods before shutting off the water supply to the home or building.

[0010] In U.S. Pat. Nos. 5,979,493, 6,209,576, 5,920,265 discloses timing and or counting the predetermined gallons of water before shutting down the water supply to the home or building.

[0011] In U.S. Pat. No. 6,317,051 discloses timing the water as well as placing a listening device in the waste pipe in order to hear if there is water running in the waste pipe simultaneously with the running of the water from the Potable pressurized water line.

[0012] In U.S. Pat. No. 5,007,453 discloses a system that also places water sensors at or near the water dependent appliances in order to count the gallons that pass through each sensor, sending the information to the main computer in order to store data from each water dependent appliance so that when that particular appliance request water, it will start counting gallons until it reaches it “usual” use of gallons of water for that appliance. If it exceeds that number, it will then shut the water off to the system. Unfortunately, if you decide to shower, water the grass or plants, wash the car, longer than usual, then this system could automatically shut the supply of water off to the house or building prematurely. Other patents disclosing apparatus and systems for preventing of shutting off fluid flow are disclosed in U.S. Pat. Nos. 4,735,231; 3,506,033; 2,160,766; 2,012,351; 3,800,827; 1,173,966; and 1,956,010.

[0013] All the abovementioned patents are incorporated herein by reference.

[0014] All the aforementioned patents disclose systems for preventing fluid flow in one situation or another, a need still exist for a system which is capable of minimizing the leakage of conductive fluid into a home or building simply and inexpensively at all times, twenty four hours a day, three hundred and sixty five days a year, whether the user is present or away. Including these benefits, but not limited to them, the ability to manually shut down your water supply for whatever reason by pushing a button on the centrally located control panel. Always knowing the status of the system by reading the centrally located control panel. By using a D.C. powered system to not only provide safety, but also to save on power cost. Including the ability of the system to notify the user by way of telephonic communication of a automatic shut down of the water system to the home or building, due to a leak detection, and or the excessive use of water, and also the ability for the user to shut the water supply off to the home by telephonic communication for safety, or for excessive water usage, without using a security service agency, saving time and the monthly charges of that service. Never having to worry about the main water supply valve freezing up, with the automatic valve cycle system built in. Minimal moving parts, to prevent frequent servicing of the system. A system that will also protect freezing water pipes from leaking as well without additional equipment.

[0015] Whatever the precise merits, features and advantages of the above cited references, none of them achieve or fulfills the purpose of the disclosed “Conductive Fluid leak detection system and automatic shut off valve”, the present invention, and is an improvement over all prior art.

SUMMARY OF INVENTION;

[0016] The present invention addresses the aforementioned problems by providing a Conductive fluid flow supply system that minimizes conductive fluid leakage whenever a leak is detected in a fluid line. In its broadest sense, the object of the present invention is to provides a method for controlling forward conductive fluid flow between a first point (example; water flow sensor out side the home or building) and a second point (water sensors placed in or at the ends of the water dependent appliances) of a pressurized conductive fluid line. The method includes detecting conductive forward fluid flow at the first point and continuing to allow the forward fluids flow to the second point(s), when conductive forward fluid flow at the second point(s) are also detected. (ie; allowing the main water line shut off valve to remain in its “Open” position) The method further includes preventing conductive forward fluid flow (by way of shutting off the main water line valve) at the first point if conductive forward fluid flow is detected at the first point and not detected at the second point(s). This invention is designed to detect conductive fluid leaks in a pressurized conductive fluid system. One example of this is the water supply to a house or commercial building. This low voltage system is designed to detect the flow of water or any conductive fluid through the main supply to the building.

[0017] This is accomplished by a system comprising of (example) a “water flow sensor” located at the main inlet outside the home or building. There are also conductive fluid detecting sensors in or at the end of every Water Dependent Appliance in the building (i.e. faucets, shower heads, toilets, appliances, hose bibs, etc . . . ) that detect when conductive fluid (water) is present and flowing from the correct and or desired location. This system also comprises an “electrically actuated “on-off” valve” located near the “water flow sensor” at the main water inlet just outside building.

[0018] The disclosed automated valve comprises of a valve that is not a normally open or normally closed solenoid actuated valve. This valve is designed to maintain its open or closed position, without the requirement of electrical power to maintain that position. (Power is required to move from one position to the other, i.e. open or closed)

[0019] The circuitry of this invention will be referred to from this point on as the Brain(s) of the system. The Brain(s) will be placed in a Control Panel in an easily accessible location in the building. The visible Control Panel comprises of a panel that will house some or all of the circuitry that runs the system as well as indicating LED's, Manual Valve Open-Close, Reset Button, an All Power Off Button, an Automation System Off/ON Button, an Numerical keypad, a user number set button, an Timer Reset Button, an Digital Display Panel, and a Audible Alarm.

[0020] The LED's are designed to help notify the user of the current system status. For example; a solid Green light could indicate that the system is on, the valve is open, and no leak is detected. A solid Red light could indicate that the main valve has been shut off “Manually”, or Automatically due to excessive water usage, and not a leak detection. A flashing Red light could indicate that the system has been “Automatically” shut down due to a detected conductive fluid leak.

[0021] The Manual Open-Close Reset Button could be used as to not only allow the user to Manually Shut Off the fluid supply to make any desired repairs or improvements, but also could allow the user to Re-Open the valve after an “Automatic Shut Off” due to a conductive fluid leak detection.

[0022] The All Power Off Button could allow the entire system to be turned off, allowing for any desired repairs or adjustments.

[0023] The Automation System On/Off Button could allow the user to shut down just the “Automated” portion of the system. This is to allow for the filling of a new water heater or to bleed the fluid lines of air without a Premature Automated Shutdown of the water flow. The Timer Reset Button(s) could be used to reset the timer(s) that starts, when the water is being requested.

[0024] The numerical pad is to be use in conjunction with the user number set button, in order for the user to set and store for example, the phone numbers from which he could be contacted at in case of a automatic shut down of the water supply, or excessive water usage. Or the code that he could store for, an over the phone, “manual” shut down or re-open of the main water valve to the home or building, and to set the timing modes of said timers.

[0025] Use Example 1: In a home, commercial building or apartment complex the water system could work as follows. When water begins to flow in the main water line, the main water line Flow Sensor, located next to the Main Shut Off Valve prior to the supply lines entrance to the home or building, would sense the water's flow, and in turn send a signal to the Brain(s) indicating the flow of water. The Brain(s) delays while automatically begins looking for a signal from one or more of the Moisture Sensors located in or at the end of every Water Dependent Appliance in or on the building. (These moisture sensors can be hard wired or wireless) If the Brain(s) receives a signal from one or more Moisture/Water Sensors, located in or at the end of every Water Dependent Appliance within a designated time period (time delay adjustments can be made from example 0.5 to 5.0 seconds) the system and Main Water Shut Off Valve will remain in its normal “Open” status and the Green light on the Panel will remain lit.

[0026] If the Brain(s) receives a signal from the main water line Flow Sensor indicating water flow in the main water supply line, and does not receive a signal from one or more of the Moisture/Water Sensors located in or at the end of the Water Dependent Appliances within the designated time period, (example 0.05-5 seconds) the system will automatically send power to shut off the Main Water Shut Off Valve. This shuts down all water from entering the home or building and keeps any resulting damage to a minimum. A flashing Red light then replaces the solid Green light, as well as a audible “beeping” signal indicating the automatic shut down.

[0027] This intern would prompt a (user programmed) Telephone Notifier, to notify the user or building owner, (by way of telephonic communication anywhere in the world) of the automatic shut down of the water system due to a conductive fluid leak detection. After locating and repairing the leak, the user would turn off the Automated portion of the system and reset the Main Water Shut Off Valve to the “open” position, redisplaying the solid Green light in place of the flashing Red light. Next the user would bleed the system of any air, and then return the Automated system to normal operating status.

[0028] If the user wishes to do repairs or maintenance in the building that requires the water to be shut off, or just wishes to turn the water off while away on an extended vacation, the Manual On-Off Button may be used to turn the Main Water Shut Off Valve to the “off” position eliminating the flow of water to the building. This causes a solid Red light to be displayed in place of the solid Green light.

[0029] If the system's main shut-off valve is shut down for any reason, and the main power source is interrupted for any reason, the D.C. powered main fluid shut off valve would remain “closed”. As stated earlier, the main fluid shut off valve does not require power to maintain its “closed” position. The opposite also applies; if the system is operating at normal status and the main power is interrupted, the main fluid shut off valve will remain “open” allowing normal water usage. It is believed that the “Conductive fluid leak detection system and automatic shut off valve” is the only conductive fluid leak detection device or apparatus that includes this feature.

[0030] In addition the system utilizes a battery back up power supply to continue monitoring the water system in the event of an interruption of the main power. While using battery power the system continues to function normally, including shutting off the main fluid shut off valve in the event of a detected leak. Battery life will be dependant upon battery size and individual systems power requirements. The battery power supply is constantly being trickle charged during normal (main) AC powered service, to maintain optimal power and battery life.

[0031] The system Brain(s) utilizes an internal clock/timer allowing it to track the amount of time between main fluid shut off valve movements. If the valve has not been moved within a designated period of time, the system will automatically close and reopen the main fluid shut off valve, maintaining freedom of movement. The clock/timer will automatically reset itself every time the main fluid shut off valve is closed for any reason, whether it is “automatically” moved, or “manually” moved.

[0032] In addition the system utilized timer(s) for water conservation purposes. If the water has been running for an (user set) extended period of time, due to a yard sprinkler left on, or a (left “on”) pressurized garden hose unknowingly ruptures etc . . . ,, The timer would time out (example; 60 min.) and prompt a distinct audible signal on the Control Panel to notify the “present” user of the excessive water use. When the distinct audible signal begins, this prompts another phase of (user set) timing to begin, and when it times out, (example; 15-20 minutes after the distinct audible signal has begun) this will prompt the (user set) telephone notifier to notify the “non-present” user by way of telephonic communication, of the excessive water usage. When the telephone notifier begins, another phase of (user set) timing starts, and when it times out (example; 15-20 minutes after the phone notifier has prompted) it will automatically turn “off” the water supply to the home, if no action is taken within that (user set) time period. (such as resetting the timer, terminating the water usage, or shutting down the water supply to the home or building by way of telephonic communication using a user set code, from anywhere in the world) This intern lights the solid Red light replacing the solid Green. The “Water Usage Timing” portion of the system can be “Reset” to start the timing periods over again, (at any time) by pushing the Reset button on the “Visible Control Panel”, in case the user desires the water usage to continue past the (user set) times programmed into the circuitry. It is believed that the “Conductive Fluid leak detection system and automatic shut off valve” disclosed is the only fluid leak detection device or apparatus that includes this feature.

[0033] In addition the “Conductive Fluid leak detection system and automatic shut off valve” system disclosed also utilizes a system for controlling the water system fluid flow, using a (user set) telephonic code, to turn the water to the system Off or On from any push button telephone, anywhere in the world. It is believed that the “Fluid leak detection system and automatic shut off valve” disclosed is the only fluid leak detection device or apparatus that includes this feature.

[0034] Use Example 2: In a larger commercial facility or an apartment complex the system can utilize multiple shut off valves, sensors and a larger control panel (which utilizes a Brain and an individual set of switches, buttons and LED's for each unit or building located in an easily accessible area for the management to observe) to isolate and identify multiple portions of a facility or individual apartment units, allowing a leak to be shut off in one unit or building while maintaining normal service to all others. It is believed that the “Fluid leak detection system and automatic shut off valve” disclosed is the only fluid leak detection device or apparatus that includes this feature.

[0035] Using the optional phone notifier built into the system, the system can be set to automatically notify the user/management when an automated system shutdown or (user set) excessive water usage has occurred. Phone notifier will alert the user by phone or pager service with a user defined message, or numerical code. It is believed that the “Fluid leak detection system and automatic shut off valve” disclosed is the only fluid leak detection device or apparatus that includes this feature.

[0036] Use Example 3: Any type of conductive fluid system that the user wishes to monitor can utilize the same options as the above examples. (I.e. pipelines, sprinkler and irrigation systems, oil field or chemical lines, and frozen pipes etc . . . )

[0037] In Summary Conclusion I contend that my invention differs from all others in many ways including but not limited to:

[0038] 1. My electrically actuated valve requires no power source to maintain its open or closed position, as opposed to a solenoid actuated valve which returns to its original position during a loss of power. This results in far greater energy efficiency as well as maintaining the desired open or closed position during an interruption of power.

[0039] 2. The battery back up allowing for continual system monitoring even in the event of a loss of electrical power.

[0040] 3. Does not rely on pressure switches, timing fluid usage, floor based moisture sensors, or the counting of gallons to operate.

[0041] 4. Has hard wired and wireless moisture sensing options.

[0042] 5. Automatically closes and opens valve(s) at predetermined intervals to maintain freedom of valve movement.

[0043] 6. Has a control panel to view and operate the system with a touch of a button(s).

[0044] 7. Monitors the entire fluid system from line entry to all desired fluid exit points.

[0045] 8. Contacts the user (when the user is away) by way of telephonic communication of a automatic shut down of the main water supply valve due to a water leak detected, without a monthly security company charge.

[0046] 9. Contacts the user (when the user is away) by way of telephonic communication of excessive water usage, without a monthly security company charge.

[0047] 10. The option of shutting off the main water shut off valve by way of telephonic communication.

[0048] 11. A warning audible signal of excessive water usage.

[0049] 12. A warning “beeping” audible signal of an automatic water supply shut down, due to a leak.

[0050] 13. The ability to connect numerous systems together, to monitor an entire apartment complex, by either building by building, or each and every apartment individually.

[0051] 14. And controls leaks in broken frozen pipes, with out the requirements of additional equipment.

DETAILED DESCRIPTION OF THE PREFERED EMBOBIMENT

[0060] As previously observed, provided herein is a system for closing a valve to shut off a pressurized conductive fluid supply in the event of a pressurized conductive fluid leak. This system is shown in FIG. 1 though FIG. 7.

[0061] 1) Automated System “On” a Leak Detected & Auto Shut Down . . . ,

[0062] When water in FIG. 1 passes through the in-let 5 and continues through the ball 1 of the main water valve, of the 12 volt D.C. Powered motor 2 located in the waterproof control cover 6 of the Automatic Shut-Off Valve, which is in an “open” position, and the lever 3 is activating switch(s) 8A which switches polarity on the D.C. motor 2, (to an open state) as well as illuminates in FIG. 3 on the control panel, the Green LED 21, by way of electrical connecting wires in FIG. 1 connected to the 12 volt input 9 located on the side of the waterproof control cover 6. The water then continues on to in FIG. 2 the in-let 10 of the flow sensing device, or in-line flapper valve, (which also includes a clean out access hole 15) which forces the pivotal valve flap member 11 forwards having attached thereto a magnet 12 away from the casing 16 and the magnetically responsive switch 13 which switches states when the magnet is moved from a first position to a second position by forces exerted by flowing water. In FIG. 6 the circuitry is continuously receiving A.C. power to it's transformer 44 which turns the A.C. power into 12 volt D.C power, and continuously charging the 12 volt battery 45. This D.C. voltage powers the flow sensing device, or in-line flapper valve 56 as well as the monolithic bipolar integrated circuit designed for use in fluid detection 46, which passes an A.C. signal through the entire water supply pipe system, which includes the, in FIG. 4 in-let 32A of the water dependent faucet, which is connected to the main water supply line. If the water flows through the, in FIG. 1 the in-let 5 and the ball 1, (which is in a “open” position) of the main water shut off valve and on to in FIG. 2 the in-let of the water flow detector, or pivotal flapper valve, which forces the pivotal valve flap member 11 that is connected to the casing 16, forwards having attached thereto a magnet 12 away from the magnetically responsive switch 13 which switches states when the magnet is moved from a first position to a second position by forces exerted by flowing water. The water continues through the out-let 14, as the magnetically responsive switch 13 sends a signal to the, in FIG. 6 the decoder 47 telling it that water is flowing. The signal continues to the on-delay timer 48, which begins the count down from it's predetermined set time. If water does not pass through one of the sensors 55 on the water dependent appliances,

EXAMPLE 1

[0063] In FIG. 4 thereby passing through the faucet's in-let 32A and on through to the faucets out-let 32B, and through the isolating adapter 33, which holds the aerator, and isolates the main water supply line from the corrosive resistant, conductive connecting washer 34, which is designed to slide over the isolator, having an A.C. signal attached to it, and to remain in place, and the corrosive resistant, conductive end cap 35 which is designed to be removed and replaced without disconnecting the A.C. signal that is connected to corrosive resistant, conductive connecting washer 34, because the corrosive resistant, conductive end cap 35 holds the clean out screen for easy screen clean out. When screwed on tightly, it makes contact with the corrosive resistant, conductive connecting washer 34, also making the corrosive resistant, conductive end cap 35 connected to the A.C. signal. It also incorporates a cross section member for insurance that water cannot pass through it without touching the sides, or the cross section member for assurances that there will be no mis-readings. So when water passes through the corrosive resistant, conductive end cap 35, it will use the main water supply line and the corrosive resistant, conductive end cap 35 as two “probes”, and the detector determines the presence or absence of the fluid between the “probes” with the resistance internal to the integrated circuit.

EXAMPLE 2

[0064] In FIG. 5, thereby passing through the shower head sensors in-let 36 which is also connected to the A.C. signal running through the main water supply line therefore also sending the A.C. signal through it, and on through the non-conductive isolator 37, which has a water chamber, and a water escape hole, which is plugged by the non conductive water stop 39, which is held into place with a spring 40, thereby stopping the water from moving forwards through the escape hole of the non conductive isolator 37 when the water is not being requested from that location. If water is being requested from that location, then the water would push the water stop 39 forwards, thereby allowing water to escape from the first non conductive isolator 36, and into the second non conductive isolator 41, which has a, that slides over the second non conductive isolator 41, and is also connected to the A.C. signal 42. The water would then go on through the showerhead, and onto the waste pipe. When the corrosion resistant conductive cover 43, has been slid over the second non conductive isolator 41, and the shower head is screwed up tight onto the end of the second non conductive isolator 41, it also makes contact with the flat end of the corrosion resistant conductive cover 43, which is also connected with an A.C signal 42, thereby also connecting the conductive showerhead to the A.C. signal. When water now passes through the showerhead, it actually becomes part of our water sensor. By using the in-let 36 of the showerhead sensor, and the showerhead its self (being connected to the flat end of the A.C. signal connected 42, corrosion resistant conductive cover 43) as the two “probes”, the detector will determines the presence or absence of the fluid between the “probes” with the resistance internal to the integrated circuit.

[0065] If water does not pass, in example 1, FIG. 4 through the two so called “probes” 32A and 35, and in example 2, FIG. 5 through the so called “probes” 36 and 43 (and the shower head) then the connection will not be made, thereby not sending a signal to the circuit, in FIG. 6, the decoder 47. The on-delay timer 48 would then would time out, and intern send power to the shut off valve relay 49, the phone notifier 51, and the audible signal 57, at the same time. When the shut off valve relay 49 receives power, it sends the power to the main water valve 54 via in FIG. 1 power connection 9, which interns in FIG. 6 turns the main water valve 54 to the closed position in FIG. 1, via the 12 volt D.C. motor 2, and the gear box 4, intern turning the ball 1 from a open position to a closed position in it's valve casing 7, intern terminating the water supply to the building or house. Which also change the position of the, in FIG. 1, lever 3 from activating the “open” switch 8A to activating the closed switch 8B. This intern prompts power to be sent to the, in FIG. 6 LED relay 53 to send power to the control panel 50 and In FIG. 3 illuminating the red flashing LED 18, and illuminating the visual screen 22 to indicate the status of the system. When in FIG. 6 the phone notifier 51 receives power, it notifies the user by telephonic communication, in FIG. 3 with a user set number 31 that there was a leak detected; and the system was automatically shut down. When, in FIG. 6 the audible signal 57 receives power, it starts to beep continuously until the system is reset by, in FIG. 3. the reset button 27.

[0066] 2) Automated System “On” with no Request for Water & no leak Detected;

[0067] The pressurized conductive fluid control system of the present invention, installed for Example; A water system in a home or building, in a “Automated System on” mode, and no water is being requested, one sees that in FIG. 1 the “Main” incoming water in-let 5, which is typically pressurized, would allow water to passed through the Ball 1 of the D.C. Powered 9 motor 2 Automatic Shut-Off Valve, which is in an “open” position, and lever 3 is activating switch 8A which switches polarity on the D.C. motor 2, (to an open state) if the water is not in motion (i.e. water is not being requested or no a leak in the main water supply line) then, in FIG. 2 the water flow detector, or in line flapper valve's pivotal valve flap member 11, has remained in it's home position, seated upon the casing 16, keeping the magnetically responsive switch 13 in its normally “closed” position. This also illuminates in FIG. 3 on the control panel, the Green LED 21, which lets the user know that the automated system is “on” and no leak is detected.

[0068] 3) Automated System “On” Request for Water & no Leak Detected;

[0069] When one or more of the water dependent appliances in FIG. 6, is requesting water, which are equipped with a water sensor 55 installed in each one, water starts to move forwards in the main water supply line into, in FIG. 1, the in-let 5 of the main water valve. When it passes through the “Ball” 1 and on through to the, in FIG. 2 in-let 10 of the flow sensing device, or in-line flapper valve, which forces the pivotal valve flap member 11 forwards having attached thereto a magnet 12 away from the magnetically responsive switch 13 which switches states when the magnet is moved from a first position to a second position by forces exerted by flowing water. At which point in FIG. 6 the decoder 47 receives the signal from the, in FIG. 2 the magnetically responsive switch 13 telling it that water is in motion. In FIG. 6 the decoder 47 waits a predetermined amount of time from the on delay timer 48 for a signal from one or more of the moisture sensors 55 installed in the water dependent appliances. When receiving a signal from one or more of the water sensors 55 located on the water dependent appliances, it neutralizes the decoder 47 from sending power to the shut off relay 49 and shutting off the main water valve 54 ultimately keeping the, in FIG. 3 green LED 21 illuminating and the water supply to the home or building on and pressurized.

[0070] 4) Water is Running, no Leak Detected, Water Conservation Timer;

[0071] This system works the same as in # “3) Automated system “on” request for water & no leak detected” but for example a hose bib (which also has a water sensor in it or attached to it) has pressurized a garden hose for the purposes of watering plants, grass, etc.. or washing a automobile, has been forgotten and left in the “on” position. If the pressure in the garden hose builds up so great as to create a split in the hose, then water would be running for a undesirable over extended period of time, not only running up the water cost of the home or building, but also wasting an enormous amount of water. When the water is in use in the home or building, this prompts a, in FIG. 6, timer 52, that is, in FIG. 3 user set 31, that starts a count down (example 60 minutes). When, in FIG. 6 the timer 52, reaches zero, it prompts an solid audible signal 57 to start, to warn the “present” user of the extended water usage. When the solid audible signal 57 starts, it, in FIG. 3 can be reset 27 to restart it's counting over again if the water usage is desired, or if the water usage is terminated, it will automatically stop signaling, and wait until the water is in use again to re-prompt. If the, in FIG. 6 audible signal 57 starts, it prompts another timing 52 mode, and if the water usages is not terminated, or, in FIG. 3 it is not reset 27, then after, in FIG. 3 a user set time 31 (example, another 20 minutes past the, in FIG. 6 audible signal 57) the, in FIG. 6 phone notifier 51 will automatically notify the user, in FIG. 3 with a user set number 31 by way of telephonic communication anywhere in the world, of the excessive water usage. The user then has the option to turn the, in FIG. 6 main water valve 56 off manually by way of telephonic communication 59. If the user does in fact option to manually turn the water supply off by way of, in FIG. 6 telephonic communication 59, using a, in FIG. 3 user set code 31, then this will send power to the shut off valve relay 49, and to the main water valve 54 via in FIG. 1 power connection 9, which interns in FIG. 6 turns the main water valve 54 to the closed position in FIG. 1, via the 12 volt D.C. motor 2, and the gear box 4, intern turning the ball 1 from a open position to a closed position in it's valve casing 7, intern terminating the water supply to the building or house. Which also change the position of the, in Fig.1, lever 3 from activating the “open” switch 8A to activating the closed switch 8B. This intern prompts power to be sent to the, in Fig.6 LED relay 53 to send power to the control panel 50 and In FIG. 3 illuminating the solid yellow LED 20, and illuminating the visual screen 22 to indicate the status of the system.

[0072] If the user does not, in FIG. 3 reset 27 the, in FIG. 6 timer 52, by way of, In FIG. 3 manually 27, terminating the water usage, or by way of, in FIG. 6 telephonic communication 59, then another timing 52 period will prompt after the telephonic communication 51 was prompted. When this timing 52 period (example another 10 minutes) has timed out, it will automatically send power to the shut off valve relay 49, and to the main water valve 54 via in FIG. 1 power connection 9, which interns in FIG. 6 turns the main water valve 54 to the closed position in FIG. 1, via the 12 volt D.C. motor 2, and the gear box 4, intern turning the ball 1 from a open position to a closed position in it's valve casing 7, intern terminating the water supply to the building or house. Which also change the position of the, in Fig.1, lever 3 from activating the “open” switch 8A to activating the closed switch 8B. This intern prompts power to be sent to the, in FIG. 6 LED relay 53 to send power to the control panel 50 and In FIG. 3 illuminating the solid red LED 19, and the solid yellow LED 20 simultaneously, as well as illuminating the visual screen 22 to indicate the status of the system. When in FIG. 6 the phone notifier 51 receives power, it notifies the user by telephonic communication, in FIG. 3 with a user set number 31 that there was excessive water usage, and the system was automatically shut down.

[0073]5) Keeping the Main Water Shut of Valve Moving Freely;

[0074] The enclosed invention also has a, in FIG. 6 preset timing 58 period built in to the system. This timer 58 starts counting after the last main water shut off valve 54 movement has occurred, and automatically resets itself, every time the main water shut off valve 54 is moved from an open to a closed position, or a closed to an open position. If the main water shut off valve 54 has not moved in a predetermined period of time (example 4-6 months) then the timer 58 will time out, and automatically send power to the shut off valve relay 49, and to the main water valve 54 via in FIG. 1 power connection 9, which interns in FIG. 6 turns the main water valve 54 to the closed position in FIG. 1, via the 12 volt D.C. motor 2, and the gear box 4, intern turning the ball 1 from a open position to a closed position in it's valve casing 7, and then immediately re-open the Main water shut off valve 54, to it's normal “open”, position. The timer 58 then will reset its self and start the timing cycle all over again.
